摘要: CdS sensitized NiO electrode was used as the photoactive cathode in a photoelectrochemical cell for water splitting, avoiding the use of a sacrificial electron donor. Photocurrent increment under visible light irradiation was observed after integration of [Co(dmgH)₂(4-Me-py)Cl] (1) to the photocathode, suggesting 1 could accept electrons from photoexcited CdS for water reduction and NiO could move the holes in the valence band of CdS to anode for water oxidation.
